Second, this is the introduction area. This is where you say "Hey, I'm Tex from Texas and I'm a ________.

If you need help, you should post a thread in the appropriate area.

AOP Residential if you're a homeowner seeking assistance

Tech to Tech residential if you're a tech seeking help with a problem.

Also, as I said earlier, this isn't a DIY forum, so the information that is divulged in the open forums tends to be limited. If you're a tech in the trade, you'd do well to make a few posts (15, I think) and apply for Professional Membership and access to the closed portions of the site where in-depth technical information is exchanged.

Well, I have a couple of ideas that need a closed forum, so work on becoming a pro member, and ask this in the Pro residential forum.
